Abstract

SE PRESENTA UN METODO Y UN APARATO PARA MOLDEAR UN ARTICULO DE MATERIAL ELASTOMERICO CON SIMETRIA CIRCULAR Y ABIERTO POR AMBOS EXTREMOS, PARTICULARMENTE PARA LA PRODUCCION DE FUELLES PROTECTORES PARA VEHICULOS. EL APARATO COMPRENDE UN TROQUEL (10) QUE COMPRENDE UNA PARTE EXTERIOR (12, 14) Y UNA PARTE INTERIOR (16) ENTRE LAS CUALES SE DEFINEN UNA CAVIDAD DE MOLDEO (24) Y UNA REGION DE INYECCION (28). EL ARTICULO (74) DE MATERIAL ELASTOMERICO QUE SE FORMA EN LA CAVIDAD DE MOLDEO (24) PERMANECE ANCLADO A LA PARTE DEL TROQUEL (16) DESPUES DE QUE LA PARTE EXTERIOR (12, 14) HA SIDO ABIERTA. ANTES DE QUE EL ARTICULO (74) SEA EXTRAIDO AUTOMATICAMENTE DE LA PARTE DEL TROQUEL (16), SE SEPARA POR MEDIO DE UN ELEMENTO (60) UN CASQUETE DE DESECHO (76) FORMADO POR EL MATERIAL QUE SE SOLIDIFICA EN LA REGION DE INYECCION (28).A METHOD AND AN APPLIANCE IS PRESENTED FOR MOLDING AN ARTICLE OF ELASTOMERIC MATERIAL WITH CIRCULAR SYNTHRIA AND OPEN BY BOTH EXTREME, PARTICULARLY FOR THE PRODUCTION OF PROTECTIVE SPRINGS FOR VEHICLES. THE APPLIANCE INCLUDES A TROQUEL (10) THAT INCLUDES AN EXTERIOR PART (12, 14) AND AN INTERIOR PART (16) BETWEEN WHICH DEFINE A MOLDING CAVITY (24) AND AN INJECTION REGION (28). THE ARTICLE (74) OF ELASTOMERIC MATERIAL THAT IS FORMED IN THE CAVITY OF MOLDING (24) REMAINS ANCHORED TO THE PART OF THE TROQUEL (16) AFTER THE EXTERNAL PART (12, 14) HAS BEEN OPENED. BEFORE ARTICLE (74) IS AUTOMATICALLY REMOVED FROM THE PART OF THE TROQUEL (16), A DISPOSAL CASE (76) IS FORMED BY A MATERIAL THAT IS REQUIRED IN THE INJECTION REGION (60) 28).
